Florida man Christopher Chaney, who had pleaded guilty to hacking the email accounts of Scarlett Johansson and other celebrities, should serve 71 months behind bars and pay more than $150,000 in restitution costs, federal prosecutors say.

The 35-year-old Jacksonville resident's actions had led to the leak of nude and other explicit photos of the stars. He had made his guilty plea on March 26 after striking a deal with prosecutors. He had faced a maximum punishment of 60 years in federal prison. He is due to be sentenced in July.

Chaney should also pay the AFTRA actor's union's Health Fund $10,374.59 as well as a "special assessment" of $900, the memorandum states.

"Based on his past employment history which consists of only temporary clerical jobs and periods of unemployment, however, it is unlikely that defendant will be able to repay any significant amount to the victims in this case," the prosecutors add. "The existence of a large restitution amount also militates in favor of a significant sentence in this case."

Mila Kunis was also previously named as one of the celebrities who had her email account hacked into by Chaney. However, prosecutors say there is no evidence that he had stolen or published nude photos of her.

The memorandum also states that before he hacked into celebrities' email accounts, Chaney had broken into the accounts of non-famous women, including a girl who "was underage for part of the 11 years" that he was "victimizing" her. He has not commented. Prosecutors quote the unnamed person as saying that Chaney posted nude pictures of her on an adult website.

They also say that the federal agents found eight photos depicting child pornography on his computer.

As part of his plea agreement, Chaney agreed to "forfeit his computers and related devices seized during the investigation, to pay restitution to all of the victims for any losses they suffered and to comply with strict restrictions regarding his future use of computers and computer-related devices."

"It started as curiosity and it turned into just being addicted to seeing behind the scenes of what was going on with these people you see on the big screen every day," Chaney told Fox 30: Action News Jacksonville after his arrest in October 2011. "I was almost relieved months ago when they (the police) came in, took my computer, and told me what was going on, that they knew - because I didn't know how to stop doing it myself."

"I deeply apologize (to the victims)," Chaney added. "I know what I did was probably one of the worst invasions of privacy someone could experience, and these people don't have privacy to begin with. I was in that slither of privacy that they do have. And I have had six months to think about it and it eats at me."
